Display manufacturers often struggle to measure viewing angles, light leakage, and uniformity accurately. Traditional measurement tools capture only straight-line light, missing how light behaves at different angles.

A conoscope lens solves this by collecting angular light information from displays and optical surfaces in a single measurement. This helps engineers evaluate true optical performance.

 What Is a Conoscope Lens?

A conoscope lens is a special optical lens used in display and optical testing systems. It captures light from multiple angles and projects it onto a sensor for analysis.

 Core Structure

• Wide-angle optical design

• High precision glass elements

• Designed for angular light mapping

• Used with imaging sensors and analyzers

This allows full angular distribution of light to be recorded.

 How a Conoscope Lens Works

The lens collects light coming from different directions and maps these angles onto a flat sensor surface.

 Angular Light Mapping

• Captures wide field of view

• Converts angle information into measurable image

• Helps analyze brightness and color shift across angles

This provides a true understanding of display performance.

 Problems with Traditional Optical Measurement Methods

Older testing methods create limitations:

• Measure only direct light intensity

• Require multiple measurements at different angles

• Time-consuming and less accurate

• Cannot map full angular distribution

These issues reduce testing efficiency and accuracy.

 How Conoscope Lens Solves These Testing Problems

Using a conoscope lens allows full angular analysis in one setup.

 Key Improvements

• Single-shot angular measurement

• High accuracy and repeatability

• Faster testing process

• Detailed viewing angle and uniformity data

This is critical for modern display quality control.

 Key Features Important for Engineers

• Wide angular capture range

• High optical clarity

• Precision alignment with sensors

• Stable measurement results

• Compatibility with display testing systems

These features improve both speed and reliability of measurements.
